The Inventor/Applicant and Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum x morifolium, typically grown as a cut flower Chrysanthemum and hereinafter referred to by the name ‘DLFMONE3’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new cut flower Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination in January, 2009 of a proprietary selection of Chrysanthemum x morifolium identified as code number db 35211, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum x morifolium identified as code number db 13000, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in July, 2010.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings since July, 2010 has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DLFMONE3’. These characteristics in combination distinguish ‘DLFMONE3’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright plant habit.     -   2. Vigorous growth habit and rapid growth rate.     -   3. Dark green-colored leaves.     -   4. Uniform and freely flowering habit.     -   5. Strong upright flowering stems with numerous inflorescences.     -   6. Semi-double type inflorescences with quilled purplish red to         reddish purple-colored ray florets and yellow green-colored disc         florets.     -   7. Relatively tolerant to low and high production temperatures.     -   8. Good postproduction longevity.

Plants of the new Chrysanthemum differ primarily from plants of the female parent selection in ray floret color as plants of the new Chrysanthemum have darker purplish red-colored ray florets than plants of the female parent selection. In addition, plants of the new Chrysanthemum have smaller inflorescences than plants of the female parent selection.

Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in ray floret color as plants of the new Chrysanthemum have darker purplish red-colored ray florets than plants of the male parent selection. In addition, plants of the new Chrysanthemum have smaller inflorescences than plants of the male parent selection.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘Delbrestar’, not patented. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Delbrestar’ in ray floret color as plants of the new Chrysanthemum have purplish red to reddish purple-colored ray florets whereas ray florets of ‘Delbrestar’ are white strongly tinged with purple in color. In addition, plants of the new Chrysanthemum have quilled-shaped ray florets whereas than plants of ‘Delbrestar’ have spatulate-shaped ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph on the first sheet comprises a side perspective view of a typical flowering stein of ‘DLFMONE3’ grown as a spray-type cut flower. The photograph on the second sheet is a close-up view of upper (top of the photographic sheet) and lower (bottom of the photographic sheet) surfaces of typical leaves (left) and inflorescences (right).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late spring in ground beds in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial cut Chrysanthemum production. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 18° C. to 25° C., night temperatures ranged from 20° C. to 22° C. and light levels averaged 8 klux. Plants were grown as single-stem spray-type plants and were nine weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
